Specification of Letters Patent.

Patented Apr. 4, 1916.

Application filed September 8, 1914 Serial No. 860,625.

To all whom it may concern:

Be it known that we, BENJAMIN Sams- BURY I'Vooos and SAMUEL LEWIS, bothof the town of Transcona, in the Province of Manitoba, Canada, haveinvented certain new and useful Improvements in Stocktails, of which thefollowing is the specification.

The invention relates to improvements in stock rails especially stockrails used on railways at switches and the object of the invention is toprovide an improved form of stock rail which will receive and protectthe advanced end of the switch rail thereby preventing the switch pointfrom becoming damaged, broken or otherwise injured by the constantpassage of trains as invariably occurs under present conditions.

I'Vith the above object in view the invention consists essentially inthe arrangement and construction of parts hereinafter more particularlydescribed and later pointed out in the appended claim, reference beinghad to the accompanying drawing in which- Figure 1 represents a planView of a portion of a main line and the switch track with our inventionapplied. Fig. 2 represents a horizontal sectional view through thetrack, the section being taken in the plane denoted by the line XXFig. 1. Fig. 3 represents an enlarged detailed face view of a portion ofthe stock rail. Fig. t represents an enlarged detailed verticalsectional view through the stock rail and switch rail, the section beingtaken in the plane denoted by the line YY Fig. 2. Fig. 5 represents anenlarged detailed vertical sectional view through the stock rail andswitch rail, the section being taken in the plane denoted by the lineZ-Z Fig. 2. Fig. 6 represents an enlarged detailed vertical sectionalview through the stock rail and switch rail, the section being taken inthe plane denoted by the line T-T Fig. 2. Fig. 7 represents an enlargeddetailed vertical sectional view through the stock rail and switch rail,the section being taken in the plane denoted bv the line P-P Fig. 2.

In the drawing like characters of reference indicate corresponding partsin each figure. V

1 and 2 represent stock rails mounted in the usual way on the ties orsleepers 3 to which they are secured permanently by the customary spikes4. I

5 and 6 represent switch rails of ordinary construction having theiradvancing ends shiftably mounted on the ties and connected to eachotherby tie bars 7 and 8, the arrangement being such that by themanipulation of the arm 9 associated with the bar 7, the advancing endsof the switch rails can be shifted in respect to the main line rails toeffect the passage of the train through on the main line or onto theswitch track as wished.

Our invention relates in no way to the construction or manipulation ofthe switch rails or in the manner in which they are shifted, residingwholly in the construction of the stock rail.

According to our invention the head of the stock rail is cut orchanneled on the switch rail side as indicated at 10 in a special mannerto receive the advancing end of the switch rail. Immediately oppositethe forward or advancing end of the switch rail, the channel cut in thehead is deepest as shown in Fig. 4 the depth of the channel beingsufficient to receive wholly the forward end of the switch rail when thesaid switch rail is thrown over against-the stock rail. At thisparticular point it is also to be noticed that the channel so cut in thestock rail provides an overhanging portion 11 which completely coversthe advanced end of the switch rail. The channel formed in the head ofthe stock rail gradually de creases in depth and increases in width fromthe point wherein the section shown in Fig. 4 is taken. to the pointwhere the section shown in Fig. 7 appears. at which latter point thechannel entirely disappears, the rail having at this latter location itsnatural contour. In actual practice the distance between these twopoints may be possibly eighteen inches or, in other words, it is equalto the distance which is customarily understood as the length of theswitch rail point. e might here remark that the advance end of theswitch rail tapers both at the sides and at the top, having the greatercross sectional area at some distance back from the point and graduallytapering and decreasing in cross sectional area from this larger sectionto the front end.

According to our invention, as obvious from the description hereinbeforegiven, the stock rail is simply cut to accommodate a portion of theforward or advanced end 0)": the switch rail as it will be seen fromobserving the various sections appearing in Figs. 4, 5, 6 and 7 of thedrawing that in Fig. 4c the channel in the head receives fully theforward end of the switch rail while in the other sectional views theswitch rail is gradually increasing in cross section while the channelis gradually decreasing in depth and increasing in width.

lVith a stock rail of the above nature inserted at a switch thehammering of the wheels of a passing train on the switch rail point isminimized to a marked extent as it will be seen the point of the switchrail is fully covered by the head of the stock rail at the point wherethe wheels are directed on the switch rail.

l/Vhat we claim as our invention is;-

In combination, a stock rail having'the Signed at Winnipeg, this 8th dayof,
